A Solbus hybrid bus operating in Częstochowa has been withdrawn from service following a series of malfunctions and unfortunate fires. To restore the vehicle, MPK Częstochowa signed a contract with Autosan, which invited three companies, including specialists from Enika, to collaborate. As part of this project, Enika supplied a high-voltage switchgear and PLC controller, improved driving dynamics, and reduced noise and gas consumption. The bus returned to service after several years of downtime. Plans also include modernizing another 24 buses.
